Plastic waste: Saving the planet, one lunchbox at a time

Sri Lanka, like most countries around the world, has a problem with producing huge amounts of plastic waste.

On a daily basis, many Sri Lankans use polythene 'lunch sheets' to wrap and transport their meals - and then throw the plastic away.

But now a 17-year-old school girl, Tharushi Widushika Rajapaksa, has invented the 'alternative lunch pack', which is reusable and biodegradable - and as a result, could help save the planet. (Reporter: Suneth Perera, BBC Sinhala)
